A garden has four sides that are all the same length. Each side measures x + 4 units. The garden's perimeter in 112. What is the

KIM [24]

The value of x = 24

Since there’s 4 even sides, add up the number you know. So, 4 • 4 = 16. Then subtract 16 from the perimeter of 112 to get 96. Lastly, divide that number by 4 to find what x equals. And, 96 / 4 = 24.

Hope this helps!

Find the product of ( 2a2– 3b2) and ( a +b2- 3z)

Bond [772]

Answer:

$2a^3+2a^2b^2-6a^2z-3ab^2-3b^4+9b^2z$

Step-by-step explanation:

$(2a^2-3b^2)(a+b^2-3z)$

Start by distributing the $2a^2$ into all of the terms in between the second parentheses.

$2a^3+2a^2b^2-6a^2z$

Next, distribute the $-3b^2$ into all of the terms in between the second parentheses.

$-3ab^2-3b^4+9b^2z$

For the sake of simpler interpretation, I separated the two above, but they are together:

$2a^3+2a^2b^2-6a^2z-3ab^2-3b^4+9b^2z$

Since the terms are already in descending order, we do not need to rearrange them.

State the trigonometric substitution you would use to find the indefinite integral. Do not integrate. (25 + x2)−6 dx x(θ) =

Thepotemich [5.8K]

Answer:

x(θ) = 5 tan θ

Step-by-step explanation:

Given that:

$\int (25+x^2)^{-6} \ dx$

we are to state the trigonometric substitution to be used to find the indefinite integral.

Suppose u is the variable and a is the constant

u = x

a = 5

So; (a² + x²)ⁿ

which is a trigonometric substitution for x = a tanθ

Then,

x(θ) = 5 tan θ
